DUSTSPRAYING MACHINE.

Application led October 17, 1313.

To alle/710m it may concern/.

Be it lrnovvnthat I, CHARLES E. JonNsoN, a citizen of the United States,residing at Kansas City, in the county of Jackson and' State ofMissouri, have invented certain new and useful Improvements in Dust-Spraying Machines; and I do declare the vfollowing to be a full, clear,and exact description ci the invention, such as'vvillenable othersskilled in the art to which it appertains to makeand usel the same,reference being had to'-` the accompanying draw ings, and to the lettersand figures ci ret erence marked thereon, which form a part of thisspecieation.

My invention relates to a dust spraying machine, and more particularlyto a niachine which is adapted for travel through a eld of, growingcotton or like plants and for spraying medicated dust onto the foilageof the plants While the machine is in inotion. l

rItis the "principal object of the invention to provide ,a 'machine ofthis character having nozzlesf'for delivering medicated dust, and-Whichare adapted for individual adjustment/to vary the delivery of the dustin accordance ,with the spacing of the rows, and for assembledadjustment to 4vary the elevation of the delivery nozzles to adapt themachine for use in a iield 'arious periods in the growth of. theplantsfthe sets of nozzles at opposite sides of the machine beingadapted for independent adjustment in order to adapt the machine for useon hillsides vor uneven ground. In accomplishing these and other objectsof the invention, I have provided improved details of structure, thepreferred toi-ms of which are illustrated in the accompanying drawings,wherein:-

Figure I is a perspective view of a dust spraying machine, constructedaccording to my invention. Fig. l1 is an end view of the same`illustratingits luse in a iield, and illustrating by dotted lines thetransverse adjustment ofthe individualnozzles. Fig. HI is a plan viewof'the machine, parts of the dust conduits Obeing removed for betterillustration. 'IV is air-enlarged Specification of Letters Patent`PatentedApr. i3, i.

detail `perspecvztive of one of the ground Wheels, showing the drivingsprocket and guard.

Referring more in detail to the parte: 'i designates ground Wheels, 2:in arched axle and 3 a `platform comprising the vehicle portion of themachine; the ground Wheels being preferably of metal, and the axlearched =to a suilioient height to ride over rows of plants at their fullgrowth and the platform braced trom the axle in order that it may hesuiciently rigid to carry the Working parts of the machine.

Mounted on theplatforrn f5 is a hopper 5, having a T 6 at its lower end;the rear portion of which opens into a conduit 7 and the forward portionof which communi- Cates with the pipe S of a blower 9, so that when theblower is in operation, medicated dust from the hopper Will be blownthrough the into the rear conduit '7. The blower 9 (which may he of anysuitable construction) is operated by a belt 1l, from a sha-Et i2, whichin turn is driven from one ot' the ground wheels by a belt 13 that runsover from a sprocket vWheel le on the shalt, and from a sprocket wheell5 that is iiXed to the Wheel 2, The hopper is also provided with astirring mechanism (not shown), which is driven by a shaft i? journaledin brachets 18 on the top of the hopper, and driven hy a belt i9 thatruns over a sprocket wllzecl 20 on said shaft and over a sprocket wheel2l onithe shaft 12, so that. all of the opera-- tive elements of rthemachine are driven primarily by one of the ground wheels through thebelt 13. t

In order to obvia'te injury 'to the plants by their being out beta-eenthe belt 13 and its sprocket Wheel, l provide a guard 23 which issecured to the platform 3 and is suspended at the inside of the groundwheel, and has a lip 24 turned over the sprocket Wheel 15 and part ofthe chain, so that as the machine travels through afield the lip 24 willpush the plants away from, the chain. also prefer to attach a plate tothe outside of the Wheel in order tc obviatethe'projection of foilagebetween the spokes of the Wheel into the gearing.

Mounted in the end of the conduit 7 that projects rearwardly from thehopper is .a T union 27, the members 28 of which are curved to dividedust delivered from the hopper and conduct same in opposite directionswith the least possible friction at the turning point. llevolublymounted in each of the members 28 and in the extended bearings'29 on theplatform 3, is a pipe 30 which extends laterali y at the back of themachine and is provided at its end with a reducing T 31; the port of theunion opposite the pipe being provided with a smaller pipe 32, and theport at right angles to the pipe-30 being providedwith a branch 33, thefit of the pipe 30 in its bea-rings being suliciently close to hold thepipe in adjusted position by friction. Pivotally of the branch 33 is anelbow 34, and mounted inthe elbow, in a plane parallel with that of thepipe 30, is a tube 35. Pivotally mounted on the tube 35 is an elbow 36,and fixed in the elbow 3G is a nozzle 37, of any suitable. type, theelbow 36 being loosely mounted on the tube 35, so that the nozzles willhang in their lowermost positions and will autprpatically adjustthemselves.' when turned from one side to the other.

Fixed on the end of the small pipe 32 is an elbow 39, having a tube 40fixed therein and extending parallel with the branch 33 and pivotallymounted on 'the end of the tube is an elbow Lil, provided with a tube 42having an elbow 43 thereon provided with a nozzle 37. '.lhe pipe 30 al.the opposite side of the machine is similarly equipped, and fixed oncach ot' the pipes 30is an arm 45, one of which has a link i-(iconnecting same with a lever 47 and the other having a. link 48connected with an arm i9 on a rock shaft 50, which is'connected with thelever 47 adjacent the first named lever, so that both lovers maybeoperated. by a person riding on the scat 5l, and each of the leversbeing provided with a quadrant 52 whereby the levers may beheld in set.position.

n' order that the machine may be con ducted through a field oi.growingplants Without injuring the plants, I run vthe tongue 54 of themachine forwardly from y Vin order to compensate-,for the additionalwdthcf the row. It is apparent thaththev the level of the platform 3, sothat it may over-lie the'plants, and use an archshaped neck yoke 55, theends of which depend finto' proper position :tor connection wit, 1ahorses collar, and also provide an varchshaped double-tree 56,thatsupports the swingle trees 5,7 at the proper elevation.

In using the machine, presuming the parts to be constructed andassembled as described,

with the hopper illcd'with medicated dust,- when the'machine is driventhrough a lield,

rotation of the ground wheel will actuatc the working parts o't' theapparatus so (hat powder within the hopper is stirred to provide a freeflow into the distributing conduit mounted on the endv tributing setsmay should be extended to their lowest limit, the.

vertical adjustment heilig scoured by rotation oi' the conduits 30 and`extensions 32 1n their bearings, under control of the levers 47; itbeing apparent that when the machine is used on taller plants, thenozzles may be elevated by revolving the distributing pipes in theirbearing, and it also being apparent that should thc machine be used on ahill side, or in any placev where the nozzles on opposite sides ci' themachine should be carried at different elevations, that the disbeadjusted independently of each other. v Iln planting cotton4 and otherplants, it is customary to space the rowsa determined distance apart,the rows of cotton plants being usually 'four feet between the rglvs,although in some .localities it is customaryto ,plant the rows live feetapart. ln order to of the machine, which is g it., Softhatih -a--cindicates 5 ft. rows and-Z), thetread adapting the machine to the twoconditions thel wheels will track three inches outside of the center in,the first case andthree inches inside of the center' inthe latter case.

lifhen the machine is adjusted for a 5t.- row, and 1t is desired to usesame 1n a held having 5 it. rows,`1t 1s only necessary to pivot theelbows 3% and 41 on the branchesY 33 and. 40, so that the nozzle tubes35 and 42 are directed away from the longitudinal center of the machine,the mount-ing of the elbows 34 and 41 on theirbranches beingsufficiently loose to allow the nozzles to dropL to operative positionby their own weight'. With .a'machine having a plurality of noz? zles ineachdistributing' set, the7 tube 35 of each successive nozzle should belengthened lll() extension pipes may be removed from the .main conduitswhen the machine is'to be thus described invention,` what I c aim as newltherem, and desire to License 2.
